spa942 sending bye message after answering the call

Hi,

Have an issue that I can't fin the reason for.

We have 10 spa942 phones.

Some time the phones sending a bye message directly after you have answer the call.

It happens approx 5 of 100 incoming calls.

Has someone any clue why?

Could it be any parameters?

I'm desperate.....

Thanks Niklas

Re: spa942 sending bye message after answering the call

Hi Niklas

Per your description seems to be related to a codec negotiation issue, it could be that sometimes your are receiving a mismatch signaling.

A ethereal trace over a phone could help to find the root of this issue. could you get one?

Regards,

Rogelio V.

spa942 sending bye message after answering the call

Dear Niklas

In my environment I have same problem: sometime linksys send BYE message (abount 7% of calls).

Could you say how you resolve this problem? Is Forced codec setting helped to you?

In my configuration Force LAN Codec:G711a
